Answer: c

Step-by-step explanation:

The two points on the line are open, so they will not be included in the solution set, which means they will be greater than or less than. No number can fit both inequalities, so it must be “or”. The only one that fits this is c.

If g(x) = x^2 + 6x with x ≥ -3, find g ^-1(0).
Dvinal [7]

Answer: 0

<u>Step-by-step explanation:</u>

g(x) = x² + 6x   ; x ≥ -3

To find the inverse, swap the x's and y's and solve for "y":

    x = y² + 6y

x + 9 = y² + 6y + 9   <em>add 9 to both sides to create a perfect square</em>

x + 9 = (y + 3)²

+/-\sqrt{x+9} = y + 3   <em>take square root of both sides</em>

-3 +/-\sqrt{x+9} = y    ; y ≥ -3

g⁻¹(0) = -3 +/-\sqrt{0+9}

        = -3 +/-\sqrt{9}

        = -3 ± 3

        = -3 + 3   ,   -3 - 3

        =     0      ,      -6

since the restriction is: y ≥ -3, then -6 is not valid
